F BOOT OR SHOE CLAMPING DEVICE.

SPEGTFIGATION forming part of Letters Patent No. 627,576, dated June2'7, 1899.

Application filed August 1, 1898- $erial No. 687,473. (No model.)

vented a new and useful Improvement in Boot-Clamps for Use in BlackingBoots or Shoes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of my invention is to provide means for holding the boot orshoe firmly in position during the operation of polishing it.

It consists of a plate or rest which is made to conform in shape withthe bottom of a boot or shoe and having a central longitudinal slot inits sole portion, said plate being provided with two sets of link-leversmovable on its top surface, each pair of links being connected togetherat their outer ends by a Vertical stud to engage with the edge of thesole of the shoe and their inner ends being connected together by ascrew-threaded bolt, which enters the slot of the plate and engages witha thumb-nut, which serves to operate in securing the parts in a fixedposition.

In the accompanying drawings,Figure 1 represents a side elevation of myimproved device as attached to a standard with the shoe in positionthereon. Fig. 2 is a top plan view of the plate, showing the position ofthe linklevers as when the sole of the shoe is clamped to the device.Fig. 3 is a side elevation of the same. Fig. 4 is an enlarged sectionalView taken in line X X of Fig. 2, showing the heel-spur as secured tothe wall of the plate.

Fig. 5 is a sectional view taken in line Y Y of Fig. 2, showing themanner of attaching the clamping-stud to the links, said stud bearingagainst the edge of the sole of the shoe, which is illustrated 'inpartial section. Fig. 6 is a sectional View taken in line Z Z of Fig. 2,showing the screw-threaded bolt and its thumb-nut in elevation.

Letters of reference correspond to similar parts in the drawings. y

A designates the plate or-rest, made of thin sheet metal and conformingin shape to the bottom of a boot or shoe, as seen in Fig. 2.

B is a slot extending longitudinally through the sole portion of theplate. Links 0 0, com- .Wardly prising two sets, each of equal length,are placed over this slotted portion of the plate in a diamond-shapeform and each pair of links having their outer ends connected togetherby the vertical studs d d (see Fig; 5) and the inner ends of each pairof links being connected, together by the screw-threaded bolts 6 8',(see Fig. 6,) said bolts projecting downwardly through the slot B andengaging the thumb-nutsff.

Grepresents the spur-stud, which is riveted to the vertical heel-wall ofthe plate, said stud being made sufficiently sharp to be readily forcedinto the front edge of the heel of a boot or shoe.

The plate A is rigidly secured to a suitabl standard or pedestal P byscrews 1', said standard having an expanded base 3, fastened by screws tto a raised platform.

The operation of my device is as follows: The boot or shoe is placed inposition on the plate or rest, as seen in Fig. 1. The operator thendraws the screw-threaded bolt e forward, which movement causes the links0 C to close inwardly and bringing the vertical side studs 01 d to bearfirmly against the edge of the sole of the shoe. The thumb-nut f is thenscrewed up tightly, after which the shoe is ready to be polished. Therear screwthreaded bolt 6 does not have to be adjusted except in suchcases that require a greater scope for clamping the sole to the shoe.When the boot or shoe is polished, the thumb-nut e is slightly unscrewedand pressed back rear- .which movement swings the linkd outward from theedge of the sole studs Fig. 2.

By my construction I form a very simple,

compact, and durable clamping device for the use of boot-blacks, at thesame time exposing all parts of the shoe, thus enabling the operator tohave the free use of both hands for the action of polishing. p

What I claim, and desire to secure by Letters Patent, is

1. The combination of the plate or rest conforming inshape to the bottomof a boot or shoe, said plate having a slot ext-ending longitudinallythrough the center of the sole portion, the two pair of link-leversmovable ina diamond-shape form upon the top'surface of the plate, eachpair of links having their outer ends connected together by the shortvertical studs which engage against the edge of the sole of the shoe,and their inner ends connected together by the screw-threaded boltswhich project downwardly through the slot of the plate and engaging theoperating thumbnuts beneath, with the spur projection riveted to thevertical wall of the plate to catch in the front edge of the heel,substantially as shown and for the purpose specified.

2. The combination of a clamping device for boot-polishing, consistingof the plate A conforming in shape to the bottom of a boot or shoe andprovided with a slot B extending longitudinally through the center ofthe sole portion, the links C C movable upon the top surface of theplate, the vertical studs (1 d connecting the outer ends of the links,the screw-threaded bolts '6 8 connecting the inner ends of the links andprojecting down- Wardly through the slot B of the plate, the

adjustable thumb-nuts ff engaging on said NATHAN B. DENISON.
